SAMSI Seminars: The Industrial Mathematical & Statistical Modeling Workshop at NC State
SAS Hall LobbyThe IMSM workshop starts with a welcome reception at 5pm on Sunday, July 14, 2019 and ends at 8pm on July 24, 2019. Location: The IMSM workshop will held in…
Dr. Indranil SenGupta, North Dakota State University, A machine learning based improvement of the Barndorff-Nielsen and Shephard model: analysis of crude oil price
A commonly used stochastic model for the derivative and commodity market analysis is the Barndorff-Nielsen and Shephard (BN-S) model. At first, an application of the BN-S model will be presented…
Differential Equations and Nonlinear Analysis Seminar: Angot Philippe, Aix-Marseille Université, Mathematical modeling and analysis towards the open problem of flow at a fluid-porous interface
We discuss mathematical modeling and analysis of the incompressible viscous flow at the interface of permeable media. Very recently, a simplified theory with asymptotic modeling and related approximations was extensively…
Irina Kogan, NC State, A Generalization of an Integrability Theorem of Darboux
SAS 4201In his monograph “Systèmes Orthogonaux” (Leçons sur les systèmes orthogonaux et les coordonnées curvilignes, Gauthier-Villars, Paris, 1910), Darboux stated three theorems providing local existence and uniqueness of solutions to first order systems of…
Philippe Angot, Aix-Marseille Universite, Recent advances on vector penalty-projection methods for low-Mach multiphase flows with strong stresses and open boundary conditions
We discuss the efficiency of recent advances on the vector penalty-projection methods including the kinematic version which uses fast discrete Helmholtz-Hodge decompositions on edge-based generalized MAC-type unstructured meshes. These methods…
Differential Equations and Nonlinear Analysis Seminar: Michele Palladino, GSSI, Italy, Modeling the root growth: an optimal control approach
In this talk we will propose a new framework to model control systems in which a dynamic friction occurs. In particular, such a framework is motivated by the study of…

Mathematics Departmental Meeting
SAS 1102Dean Chris McGahan will join us for the first 30 minutes of our meeting and will hold a Q&A session There will an ice cream served before the meeting starting…
Introduction to SIAM
The SIAM student chapter will be hosting an introductory lecture aimed at Undergraduates and Graduate students on national SIAM events, SIAM resources, and upcoming student chapter events. Cookies and coffee…
Tye Lidman, NC State, Homology three-spheres and SU(2) representations
One way to effectively show a group is non-trivial is to find a non-trivial representation. A major open question in low-dimensional topology is whether the fundamental group of a closed…
Quoc Tran-Dinh, UNC-Chapel Hill Dept. of Statistics and Operations Research, Smooth Structures in Convex Functions and Applications to Proximal-Based Methods
In this talk, we demonstrate one way of exploiting smooth structures hidden in convex functions to develop optimization algorithms. Our key idea is to generalize a powerful concept so-called "self-concordance" introduced by Y.…
Kirk Main, Let’s Talk IT: HPC Cluster
The High Powered Computing Cluster is a great resource available to all Mathematics staff, faculty, and graduate students. Unfortunately, it is underutilized due to the fairly technical use standards. In…
